Description
This is a portable measuring instrument that allows you to easily and accurately measure surface roughness.

The Surftest SJ-310 offers you the following benefits:
Skid system with touch-screen functionality and built-in printer.
It works independently of mains power, allowing you to make on-site measurements.
Easy and intuitive menu navigation.
The large 14.5 cm [5.7“] colour LCD gives you high visibility.
It performs roughness analyses conform to various international standards (EN ISO, VDA, ANSI, JIS) and customized settings.
You can store up to 10 different measuring conditions inside the SJ-310, and up to 500 with an optional SD card.
Statistical analysis and coloured tolerance judgement.
2 different evaluation conditions within 1 measurement adjustable.
You can separately password protect many functions.
It comes with support for 16 languages.
